CENTRIF UGAL FILLING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 701,466, dated June 3, 1902.

, Application filed December 6, 1900. Serial No. 38,956. (No model.)

To alt whom it may concern: Be it known that LNORBERT OEIPEK, a subject of the Emperor-of Austria-Hungary, re-

:siding at Vienna, in the Province of Lower Austria, in the'Empire of Austria-Hungary,

have. invented certain new and useful Improvements in Centrifugal Filling-Machines; and I do hereby declare the following to bea full, clear, and exact description of theinvenmarked thereon, which form a part of this specification.

This invention has relation to multiple-tube filling-machines; and it has for its object certain'features of construction whereby a large number of tubes may be filled with a granular, pulverulent, or more or less viscid substance and whereby the filled tubes can be readily removed and empty tubes substituted.

- The invention has for its further object the.

- in the tubes from that in the feed-funnel when a more or less viscid material is to be packed into tubes, and thereby preventing such material being drawn out intoa stringy form when the filled tubes are removed with their holders; but that my invention may be fully understood I will describe the same in detail, reference being had to the accompanying drawings, in which Figure 1 is a vertical axial transverse section of so much of a centrifugal-tube fi-llingmachine as will be necessary to-an' understanding of my invention. Fig. 2 is a half top plan view thereof, partly in section, the upper retaining-ringsbeing removed. Fig. 3 is a vertical'section taken on line r iof Fig. 2. Fig. 4 is a horizontal section taken on line ww of Fig. 1. Fig. 5 is an elevation, partly in section, of one of the tube-holders and showing in part the plate which carries the filling-nozzles; and Fig. 6 isa vertical section on line ma: of Fig. 2.

D The centrifugal drum may be of any suit"- able construction. As shown in Fig. 1,it comsecured to a tubular support (1, mounted on and rotating with the axially-disposed driving-shaft S. At its upper end the drumD is surrounded by a strengthening or bracing ring (1 to which is removably bolted alock ring d 'The drum D is-provided on its innor periphery with vertical guide-ribs dflequidistant from each other.

The carriers C for the tubular tube-holders H are assembled into a ring on a circular' frame adapted to be lowered into and hoisted out of the centrifugal drum D, said carriers consistingof parallelepipedal hollow bodies or carriers the inner and outer vertical walls of which have parallel rowsof holes formed therein for the introduction of thetubular tube-holders H, thevertical walls a between each two vertical rows of tube-holders being.

open or frame-like for the sake oflightness, as shown at c, partly in full and partly in dotted lines, in Fig. 3, in full lines in Fig. 4,

and at the lower part of Fig. 5.

The tube-holders H, into'which the tuhest to be filled are inserted, are of such a length thickness or external diameter that all the rings will be in frictional contact with one another when the tube-holders,with the tubes their bearings from withoutt. e., through the bearings in the outer vertical wall of the carriers 0, as shown in Figs. 3 and 4.

The bearings for the tube-holders H are of such a diameter as to allow said holders-to revolve freely, and one of them, preferably the central one, H, Fig. 3, not intended for the reception of a tube to be filled and closed at both ends, has in its outer end recesses or notches h for a key or crank, by means of which said tube can be rotated and there through all of the other tube-holders through their friction-sleeves 0 for purposespresently explained.

The tubes tto be filled are closed at one end and are of such a. length that their open end will project some distance from the innor end of their respective, tube-holders H.

(See Figs. 3 and 4.)

The described tube-holder carriers 0 are t to be filled inserted therein, are inserted into into the centrifugal drum D, as follows: The carriers are seated on a disk (Z which fits into the centrifugal drum D and has secured to its under side.a ringr of less, diameter than that of thedisk (P, which ring rests upon the bottom 01 of said drum. Between each two carriers is inserted a wedge or sector shaped spacing device A, hereinafter referred to as the spacer, which is hollow for the sakeof lightness, and some or all of said spacers have a vertical groove in the outer wall fitting the guide-ribs (P, which not only guide the'ring-frame when lowered into or hoisted out of the centrifugal drum, but also.

look the same against rotary'displacement. The spacers A also have an internal transverse web ct, perforated for the passage of a a bolt a5, extending through the bottom disk (1 and secured to the bottom ring 4" by-means of nuts or headscountersnnk in said ring, as shown in Fig. 6. These bolts 0. also extend through a top-retaining disk r of less diameter than the bottom ring 1' and overlapped by the top-retaining ring d bolted to the centrifugal drum D, as hereinbefore stated, said bolts having-at their upper end a ring a for connection with a hoisting-tackle.

. overlap adjacent feed-plates P, and thus lock bolts (1..

the same and the carriers together into a'ring on the bottom disk (i the bolt or bolts 1), that serve to lock said bars to the spacers, being screwed into the same from without andpassing through suitable eyes a of the vertical The heads of the bolts 1) lie in the vertical guide-groove in the outer wall of the spacers or in a suitable countersink, where this groove is absent, as there need not be a guide-rib for each of'said spacers. In this manner the tube-holder carriers are locked against inward radial displacement, and the ring of such can be bodily lowered into and hoisted out of the drum D.

In practice and to protect the attendants from injury the centrifugal drum is inclosed in a shell or casing E, which is'stationary, and may be bodily removable or have a removable covere, provided with a feed-aperture e, in register with a feed-funnel F, secured to the top plate 1' of the ring of carriers.

On the outer end of the carriers 0 is placed a backing-plate g and outside of this a lockplate h, wedge --shaped in vertical section, whose outer face is convex, the are being a segment of the circle described by the inner periphery of the centrifugal drum D, both plates being supported by the bottom disk 11 The manipulation of the tube-carrier ring is as follows: Before the centritugai drum is supplied with the material. to be filled into are then removed, the tube-holders H withdrawn, tubes i to be filled are inserted, and the holders returned to their carriers,with the inner open end of'the tubes tprojecting over their respective feed-nozzles'p. The backing-plates g and lock-plates h are then placed on the bottom disk d of the ring-frame, and the latter is lowered into the drum D, being guided by the guide-ribs d on its inner periphery, the look-plates hbeing finally driven home onto disk (1 thus firmly locking the ring of carriers to the centrifugal drum D.

The retainin -rin d and cover 6 are then replaced, material fed to the centrifugal drum, and the latter rotated, the tubes t'being filled bycentrifugal action. After all the tubest are filled the rotation of drum D is arrested, the ringof carriers hoisted out of the same, as before described,and the plates g and it removed. When being hoisted out of the drum, all of the feed-nozzles 19 will yet contain a small quantity of material in their innertubular part, and if the tube-holders,with their tubes, were withdrawn from their carriers quite a considerable quantity of the material con tained therein would be drawn out, if such material were more or less viscid. To avoid this, the tube H is rotated, whereby all of the tube-holders are also rotated about their axes through their f riction-sleeves, as hereinbefore described, thereby severing the material in tubes if from the material in the nozzles 12 and preventing its being drawn out into a string when the tube-holdersa re removed. The ring of carriers after being hoisted out of the centrifugal' drum may be carried to any convenient part of the room, and as'the carriers 0 can be readily withdrawn outwardly from between the spacers A carriers the holders of which contain tubes to be filled can be substituted for those removed.

In the drawings I have shown a ring of twelve carriers, eachhaving bearings fortwentyiour tube-holders. Hence in such a machine two hundred and eighty-eight tubes IIO can be simultaneously filled; but I do of course not limit myselfto this.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-' i 1. In a machine such as described, the combination with a'centrifug'al drum, of arring of interlocked carriers each carrying a multi 'plicityof open-ended tubular holders for the reception of tubes to be filled, a feed-nozzle at the inner end of each holder and means for removably locking saidrin g of carriers to the inner periphery of the drum, for the purposes set forth.
